Trickle charger comes to the rescue when long-time unused automobiles under severe weather degrade the battery’s power continuously. A trickle charger can resurrect a dead battery under certain conditions.
As batteries tend to self-discharge, keeping your automobiles unused for a long time or parking them outside under severe weather degrades the battery’s power gradually. A trickle charger generally charges a battery slowly so that it doesn’t run out of power. It even comes as a handy tool for a dead battery too.
There are different ideas of how long a trickle charger can be left on a battery. Therefore, different types have been manufactured. For instance, a trickle charger(capability of delivering 1 to 3 amperes of power) will take 20 to 24 hrs to charge a dead 12V battery to revive it in the usual state of charge.
So can a trickle charger charge dead batteries? Of course, it can. The alternator of a car allows the battery to remain active, but it cannot revive a dead battery. On the other hand, a trickle charger can resurrect a dead battery to a certain extent only when provided with a huge amount of time.
What is A Trickle Charger
The main goal of a trickle charger is to ensure to keep running a battery when not in use for a long period of time, even when it is self-discharging. However, it can bring life to a dead battery providing that it is in good condition and not thoroughly worn out. So, a trickle charger definitely can charge a dead battery.
